Natural & Healthy

Healthy Living Comes Naturally

EcoCocon panels are made of 98% natural renewable materials. Making them as close to nature as possible results in high indoor air quality with no harmful substances emitted. The entire system is permeable to vapour – it allows excess humidity to escape – and with no thermal bridges and airtight, it leaves no space for draughts or mould. Natural materials create a healthy indoor microclimate with even temperatures – warm in winter and cool in summer.

The System

Energy Efficient

Performance Hidden in Cells

Thanks to its unique cellular structure, straw has been used in construction for thousands of years. Combined with modern technology, we have succeeded in further improving its performance and achieved exceptional insulation properties. With no thermal bridges and easily achieved airtightness, reaching the Passivhaus standard has never been easier.

The System

Safe & Durable

Rely on Certified Quality

With more than 10 years of experience, our system fulfils the highest quality requirements, including the Cradle to Cradle and the German Passivhaus Institute certificate. EcoCocon ranked 4th in the first-ever global Product Innovation Challenge by the Cradle to Cradle Product Innovation Institute and received an Innovation Award 2019 for “Regionally available and renewable materials”.

The System

Fast & Flexible

Build with Ease

Our system is prefabricated in a factory under rigorously controlled conditions, allowing for very high precision. This way the panels all fall perfectly into place and with no wet processes, the whole building can be assembled in very little time compared to traditional construction. With custom-made dimensions, our panels can fit almost any building design and provide architects with creative freedom.
